    Main Processing Way of Techyour PTFE Coating

    1. Requirement on pre-treatment

    l Firstly, apply high-temperature degreasing, then wash with 1%~3% NaOH solution (60) for more than 6 minutes, dry it after water rinsing;

    l Blast with 80#~120# corundum to make the surface roughness reach 2.0μ~3.0μ, pay attention to sandblast evenly;

    l Wash with 1%~3% NaOH solution(60) for more than 6 minutes, rinse with water;

    l Wash with 1%~3% hydrochloric acid solution (60) for more than 6 minutes, rinse with water and dry.

    2. Preparation of the coating

    l Dispersion of coating: the coating must be fully dispersed before operation;

    l Viscosity adjustment: the viscosity could be adjusted according to different spray methods. Dilute with clean water if the viscosity is over high;

    l Coating filtration: filtrate the coating with screen (100mesh) before using.

    3. Application

    l The spraying environment should be dry, well-ventilated, no smoking and fire. We suggest using dedicated spray gun, elevated tank and curing oven;

    l The air compressor should be degreased, dewatered and equipped with water oil separator before using;

    l Roll the coating at 30rpm speed before using to make sure there is no sediment, and filter with 100 mesh screen;

    l Adjust atomization and oil pump capacity of the spraying gun; make sure the unit is clean and flat;

    l Preheat the substrate to 35 and spray the primer. Dry it at temperature of 120~150 for 10min-15min. Keep the thickness of primer within 12μm-18μm;

    l Spray top coating after the primer is dry and cooling to room temperature, then spray the top. Dry the unit at the temperature of 100~150 for 10~20 min, and gradually increase the temperature to 380~420. Keep for 10 min. Keep the thickness of top coat within 10μm~12μm. The thickness of two coat tally should be between 20μm~30μm;

    l The oven (or the tunnel drier) must be well ventilated; otherwise, it will lead to color change of coating.

    Main Application of Techyour PTFE Coating

    l Ecofriendly PTFE emulsion

    l Non-stick and excellent abrasion resistant

    l Excellent weatherable, salty foggy resistant

    l Excellent strong acid resistant and alkali resistant

    l Applied to iron, aluminum, ceramic, stainless steel cookware etc.
